我像是一个你可有可无的影
[wŏ xiàng shì yī gè nĭ kĕ yŏu kĕ wú de yĭng]
Translated as 'I Am Like An Optional Shadow To You', it expresses feelings of insignificance or being easily overlooked by important persons, possibly stemming from self-doubt and a sense of lack of importance to others, such as loved ones or acquaintances.
